Yet other photos from the same event appear to show the same sign with Surrey Centre Conservative candidate Sucha Thind's name. Here's a different photo from the same event but a slightly different angle:

Observant readers will note: (1) the same lectern; (2) the same Canadian flag; (3) the same "Alice Wong" election sign; (4) the same "Wai Young" election sign; (5) different "Sucha Thind" / "Tim Laidler" signs; and (6) the same Tim Laidler.

Laidler's campaign is keeping quiet – they will not even confirm they sent the e-mail in which the digitally altered photo appears, despite multiple requests for comment (including the tweet below).

Hi @LaidlerTim. Did your campaign send an e-mail to supporters on August 25th?

But a copy of the e-mail sent to Laidler's supporters on August 25th obtained by PressProgress sure looks like it came from the Tim Laidler campaign:

After being presented with before and after images of Thind's altered sign, Thind's campaign managers told PressProgress that "since we have no idea what you're talking about, we have forwarded your concerns to head office."
